MEDICINE-MEASURING TUBE.

SPECIFICATION forming part of Letters Patent No. 230,960, dated August10, 1880.

Application filed December 31, 1879.

To all whom it may concern:

Be it known that I, SAMUEL D. Mom, of Menlo Park, in the State of NewJersey, have invented an Improvement in l\Iedicine-Measurine Tubes, ofwhich thet'ollowing is a specification.

Great dit'fieulty arises in measuring small quantities of medicine,especially where the same is contained in a large bottle; and, besidesthis, the swallowingof liquid medicines of an acid character is ofteninjurious to the teeth and generally disagreeable to the taste.

My invention is made forsat'ely witlnlrawing small quantities ofmedicines, acids, or other liquids from the containing-vessel andmeasuring the same either by drops or in the containing-tube, and thetube is adapted to being introduced into the mouth and its contentspoured into the throat, so as to avoid unnecessary contactwith the mouthor teeth.

In the drawings, l igure 1 is a vertical section of the measuring-tube,and Fig. 2 is a plan at the line 1:90. Fig. 3 is a plan at theline yy.

The small tube (t isot' a convenient length to be introduced into .thebottle or vessel containingthe liquid. Its upper end is, by preference,contracted to the fine tube 1), within the receiving-measure c, and thismeasure 0 is in turn extended as a mouth-tube, (l.

The entire device is preferably made of glass, and its mode of use is asfollows: The tube (1 is placed in the mouth and the end of the tube adipped into the liquid to be taken up in a small measured quantity. Theatmosphere is exhausted sufficiently to draw theliquid up in the tube aZ), and it flows trom the upper end of I) in a very fine stream into themeasure 0, or it may drop from the returned end of Z). In eitherinstance the measure may be by drops so that the person ca easily drawthe liquid into the vessel 0 to any required extent.

To facilitate inspection the tube (1 may be curved or bent at an angleto the tube a; but generally it will be easy to observe the dropping ofthe liquid or the supply into the measure with a straightinstrument.

After the quantity has been drawn into the measure the partial vacuum isto be relieved and the air blown from the mouth, so as to empty the tubea. This does not in any manner afl'ect the liquid in the measure, andthe same is to be poured out through the tube (1 into the mouth or intoany vesselor receptacle.

This device is very convenienttbr druggists, physicians, and others, andis a cheap and reliable article that can be used to take the place ofthe ordinary small druggists measures and as a substitute for theglasstubes often employed in taking medicine.

If desired, water or sirup can be drawn into the measure before or afterthe medicine, and the drnggists measure of any desired size can be madein this manner, so as to receive different liquids in succession.

The graduations are to be of an y usual character, and I remark thatthis instrument can be Washed out with water or alcohol, drawn in, asaforesaid.

I claim as my invention- The combination, with the measure 0, ot themouth-tube d, supply-tube a, and tube 1), passing up inside the measure,substantially as set forth.

Signed by me this 3d day of November, A. D. 1879.
